Be it known that I, 'WILLARD E; SWIFT, a citizen of the United States iesicling pending application for patent on illschine for attaching lisp securing means to QHYClOFSJ Serial No. TT'LSSS, filed July 9 1913.

My invention relates to 1 3 nes for so inching ii-zip secur ng means t envelops and more particularly io 21 machine for autoinuticzill v attaching a button or washer to the body of an envelop in such position that a string or COlCl carried by the flap of the envelop may be. wrapped. about it for the purpose oi holding the lap securely closed.

T 1e machine shown in the soeomp nying di'mvings for the nurgose of illnstrai the present invention is provided with. automatic means -for reinforcing the enveloo at the point al: which the button is ettaolied, this automatic means noting simultaneously with the button attaching mechanism so that the attaching of the butson the reinforcement by means of a suitable fastener may be eompleteol in a single operation.

ohieos oi the invention is an iinpixverl form of guard to preven i jury to an ope; itoi" by the fasten-e1 set ng mechanism, automatic means being o o Y eel to move the guard out oi ihe vrey as me selting mechanism operales.

Another object of the invention is to provide access to the buttons 61 Washers during their movement through their feedia mechanism for the purpose of iiig them in case they become chsplaoenot to feed properly.

Another object of the invention 's to provide automatic means to prevent injury to an operator by the button feeding mechanism While the operator adjusting the positions of the buttons which have been disolaoecl so as not to feed. properly Another object of the invention is to grovide an improve-cl "form oi geevity lube through which t e ing their mo ting ineohen is eel as :to be e chine but, also neofiion with zhe whioi Figure 3 1? side of X3]E Z(ll1l118 oonstrnomee 1n eeooroenee W151}. my mve1-- ig. 2- is 21 ohm view of 2.. pension of 1 v B I the genie?

' The die 8 and the forward end of its hori zontal support 10 are surrounded by the guard 29, this guard serving also as a guide for directing an envelop into proper position betweenthe dieand the set to receive an eyelet. Fig. 7 shows an envelop 30 with an eyelet 31 after the eyelet has been set in proper position in the envelop; The guard 29 is'pomted at its forward end andjits' walls' 5 5 diverge rearwardly to surround the die 8 and the forwardend of the'support' 10. r envelop to receive an eyelet is -placed. with its flap 32 below the guardfand with the pointed end. of the guard'in the" openin of the envelop.
